Nanoscale 'tsunami' helps locusts tune in

The remarkable mechanism by which the tiny ears of locusts can hear and distinguish between different tones has been discovered by researchers from the University of Bristol.

Frogs without ears hear with their mouth

Gardiner's frogs from the Seychelles islands, one of the smallest frogs in the world, do not possess a middle ear with an eardrum yet can croak themselves, and hear other frogs. An international team of scientists using X-rays ...

Large moths need to hear better

Bats orient themselves through echolocation, and they find their prey by emitting calls and then process the echoes reflected back to them from the prey. Small insects reflect small echo signals, and large insects reflect ...

Researchers design sensitive new microphone modeled on fly ear

Using the sensitive ears of a parasitic fly for inspiration, a group of researchers has created a new type of microphone that achieves better acoustical performance than what is currently available in hearing aids. The scientists ...

Physical by smartphone becoming real possibility

It's not a "Star Trek" tricorder, but by hooking a variety of gadgets onto a smartphone you could almost get a complete physical - without the paper gown or even a visit to the doctor's office.

Ultrasonic sounds of the rainforest

Research aimed at developing ultrasonic microphones with insect-like sensitivity is to continue in the rainforests of Colombia and Ecuador.

Implantable medical devices powered by the ear itself

Deep in the inner ear of mammals is a natural battery—a chamber filled with ions that produces an electrical potential to drive neural signals. In today's issue of the journal Nature Biotechnology, a team of researchers ...

Eardrum

The eardrum, or tympanic membrane, is a thin membrane that separates the external ear from the middle ear in humans and other tetrapods. Its function is to transmit sound from the air to the ossicles inside the middle ear. The malleus bone bridges the gap between the eardrum and the other ossicles. Rupture or perforation of the eardrum can lead to conductive hearing loss.
